The PSG1 has a 7-round magazine, allowing for (brief) rapid firing, in contrast to the bolt-action mechanism of the regular Sniper Rifle. The PSG-1 in GTA Vice City is one of the most powerful weapons in the game sans explosive devices such as the Rocket Launcher. A full magazine will easily destroy any unarmored vehicles in the game.

Curiously, files suggest that the weapon has much less fire rate than the Sniper Rifle, as the weapon has a fire rate of 150 rounds per minute, while the Sniper Rifle has 500 rounds per minute.

Grand Theft Auto IV

The Combat Sniper rifle delivers a one-headshot kill in single player and multiplayer, unless the target is armored. It will also kill with about 3 shots to the body. It can easily take down pedestrians, drivers, motorcyclists and, with patience and extreme accuracy, take down helicopter pilots. During first-person aiming, if the player is standing, there is a noticeable movement of the scope due to Niko Bellic's breathing. This can be minimized by crouching.

It has a ten-round magazine and excellent range. The semi-automatic firing mode allows for better chances at taking out targets, especially when players misses them.

Interestingly, according to the files, the Combat Sniper appears to have a slightly lower fire rate than that of the Sniper Rifle.

HD Universe

When purchasing weapons from either Little Jacob, Terry Thorpe or Armando Torres in the Grand Theft Auto IV trilogy, the Combat Sniper is simply referred to as "Sniper Rifle". The same happens in the files, where it is also referred to as "Sniper Rifle".

Glitches

Grand Theft Auto IV

If the player keeps crouching and shooting at the same time, the weapon's rate of fire will increase.
